One of the things I love about Zheng, besides the fact that his work is mainly futa, with some of the cutest/sexiest futas and plenty of gorgeous cumshots and ahegao faces is the fact that most his futa give it and take it, they both "top" and 'bottom."
There's a good amount of "futa artists" out there these days that only depict the futa as a "top" but it feels to me a bit of a waste to have a dual gendered individual and not even make use of the other half...
